し、締付位置を調整できる。The tightening center bolt 6 passes through the centers of the flanges 3a and 3b, and its axis C 2 is orthogonal to the axes C 1 and C 3 of the pipe section. The center bolt 6 has a hexagonal head 6a at one end and a male screw portion 6b at the other end, and can be fixed to the male screw portion 6b with a tightening nut 7 and a lock nut 8 via a washer 9. Hexagonal head 6a of center bolt 6
An O-ring 10 is fitted in a bolt hole 11 formed in the case near the male screw portion 6b. As will be described later, the portion where these O-rings 10 are fitted becomes a rotating portion, and after loosening the center bolt 6, the cases A and B can be relatively rotated to adjust the tightening position.

係を調整する。The flanges 3a and 3b provided on the peripheral edge of the circular opening where the cases A and B are in contact with each other serve as a rotary sliding surface. The O-ring 10 is also fitted on the rotary sliding surface. Due to the above structure, when it is desired to change the angular relationship between the case A and the case B, one of the cases A and B is loosened after loosening the lock nut 8 and the tightening nut 7. Rotate to adjust the angular relationship.
